CHARLES BAKEHAUS, OF SIGOURNEY, IOWA.

STEAM-GENERATOR.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed March 28, 1907. Serial No. 865,035.

To all whom it may concern:

Be it known that I, GnARLEs BAKEHAUS, a citizen of the United States,residing at Sigourney, in the county of Keokuk and State of Iowa, haveinvented certain new and useful Improvements in Steam-Generators, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in steam generators.

The object of the invention is the provision of means for facilitatingtheinstantaneous generation of steam.

Another object of the invention is the improvement of the constructionof a generator, which is provided 7 with means for receiving water insmall quantities and the instantaneous generation of steam from saidwater, without the employment of tubes or lines, which are a part of anordinary generator.

With these and other objects in view, the invention consists of certainnovel constructions, combinations, and arrangements of parts, as will behereinafter fully described and claimed.

In the drawings: Figure l is a view in side elevation of a generatorconstructed in accordance with the present' invention, part of which isshown in section. Fig. 2 is a transverse, sectional view taken on line2, 2, Fig. 1, and looking in the direction of the arrow. Fig. 3 is afragmentary, sectional view of the boiler.

Referring to the drawings, 1 designates a support or frame, within whichis formed the fire-box or furnace 2. Supported upon the frame orfoundation 1, is a cylindrical shell or receptacle 3. Any suitable meansmay be employed in the furnace 2 for heating the cylindrical receptacle3, as for instance, a gasolene burner 4. Owing to the cylindricalstructure of the receptacle 3 the flames from the burner 4, or any otherheating means, are permitted to pass up around the side of thereceptacle and thereby heat the greater portion thereof. It will beobvious that if the flames are of sufficient size, owing to thecylindrical structure of the receptacle 3, the flames may come incontact with over half of the receptacle, which is not true of anordinary receptacle provided'with a flat bottom, or a bottom providedwith rounded edges; this direct contact of the flames with the greaterportion of the receptacle is an important advantage which I obtain.

My cylindrical receptacle is provided with vertical ends 5 and 5, andthis structure is of importance. The pipe 6 extends through, preferably,the central portion of the end 5, and said pipe is provided at its upperend with a safety valve 7. A comparatively large opening 8 is formed inend 5, preferably between the lowest portion thereof and pipe 6. A. door9, constituting closing means, is employed for closing the opening orport 8. This closing means or door 9 is made steam-tight. I preferably.employ this opening 8 in my receptacle 3, so that the interior thereofmay be cleaned of any accumulated scale, or, in constructing theapparatus, entrance into the interior of the receptacle 3 may bepermitted for facilitating the assembling of the different parts of theapparatus.

Extending, preferably, from the center of the end 5 of the receptacle 3,is a valved outlet steam-pipe 10.

The water or liquid is discharged into the receptacle 3 through themedium of a pipe or tubing 11. The horizontal portion 12 of the tubingis provided with a valve 13, and the vertical portion 14 of said pipe 11extends through, preferably, the extreme lower portion of the receptacle3, and this portion 14 terminates at its upper end in a horizontalportion 15, which horizontal portion 15 terminates at its outer end,preferably, in a depending nozzle 16. I preferably form the portion 15of sufficient length to place the discharge nozzle 16 near the center ofthe receptacle 3, and directly over the heating means or burner 4. Forthe purpose of making the connection between the lower portion of thereceptacle 3 and the portion 14 of pipe 11 steam-tight, l secure to theoutside of the receptacle 3, a stufling-box 17.

The receptacle 3 may be secured upon the support or framework 1 againstany independent rotary movement with respect to said support 1, byreason of the peculiar positioning and structure of the pipe 11, as itwill be obvious that fastening means, as for instance, a bracket, shownin dotted lines at 18, may be secured to any suitable support and engageor surround the lower horizontal portion 12 of-the pipe 11, therebyfixedly securing the receptacle 3 upon its support. Furthermore, bypositioning the pipe 11 in the extreme lower portion of the receptacle 3and contiguous to and between the support or framework 1 and the opening8 of the side 5, the pipe 11 will be heated by the heating means in thefurnace 2, sufficiently to warm the water contained therein, as well aspermit the portions 14, 15, and 16 of the' pipe 11 to be examinedthrough the opening 8, for keepingsaid pipe in perfect workingcondition. By reason of the positioning of the pipe 11 contiguous to thefurnace, but not in contact therewith, the water will be heatedsufficiently to increase the efficiency of my apparatus, as the waterwill be of such a temperature as to be more quickly generated intosteam, when coming in contact with the hot surface of the receptacleabove the heating means 4. Before the water enters pipe 11, it may beplaced in a heated condition in, or it may be heated in receptacle 19,as shown in dotted lines, and as this receptacle 19 is connected by apipe 11, to the valved pipe 11, the heated water from the receptacle ortank 19 will be discharged into the receptacle 3, under pressure.However, the amount of water discharged through pipe 11 into thereceptacle 3, is controlled or regulated by valve 13, so that if Idesire, water may be discharged into receptacle 3 in a certain amountand at predetermined intervals. For instance, a very small quantityevery few seconds. I may employ a pump (not shown) for retaining thewater in receptacle or tank 19, at a given pressure.

If it is desired to have the receptacle 3 comparatively dry, from oneperiod of use to another, this may be accomplished through the medium ofthe valved drain cook 20. It will be apparent that after the heatingmeans 4 has been extinguished and the receptacle is allowed to cool,such steam as is in the receptacle 3, will be condensed, and therebycause a certain amount of water to remain in said receptacle until thenext time it is used. However, by opening the valve of the cock 20, thewater will be completely drained from the re ceptacle, therebypreventing any injurious result. To

facilitate the draining of the water from the receptacle, I preferablyform, in the inner face thereof, and at the lowest portion, a shallowgroove 21 running from near the end 5 to the cook 20, and increasing indepth from said end 5 to said cock, as is clearly shown in Fig. 3.Between the end 5 and cock 20, I also form a shallow groove 21, whichincreases in depth from end 5 to said cock. Both of the grooves 21 and21 open upon the cock, and thereby cause the slightest quantity in thereceptacle to be discharged through said cock. This is an importantfeature of my apparatus, as it will enable the receptacle to be drainedcompletely, as the cylindrical structure of the same will direct all ofthe water to the grooves 21 and 21.

A suitable indicator 22 is carried by the receptacle 3, preferably uponthe upper portion thereof. When the apparatus isin operation, thereceptacle or shell 3 is sufliciently heated as to instantaneouslygenerate or flash the water into steam, thereby forming really a gas,which, when sufiicient pressure has been obtained in the receptacle 3,may be allowed to pass through the valved outlet pipe 10, forutilization.

Owing to the extremely simple structure of my apparatus, a great amountof fuel is saved. Furthermore, it is not necessary to wait aconsiderable time for the Water to heat, but steam can be nearlyinstantaneously generated as soon as the burner 4, or other suitableheating means, is started, which is of great importance, as considerabletime is, therefore, saved.

My apparatus may be used, not only for generating steam for engines, butalso for heating houses, buildings, etc.
